This invention relates to perforated recordcontrolled tabulating machines, and particularly to that type of machine used for recording and compiling information indicated by hole s punched in record cards, the information being transferred to a system of accumulators or wheels by means of analyzing devices cooperating with holes, and causing a chain of elements to be. set in motion to thereby properly tabulate and record the information indicated by the holes in the card. The type of tabulating machine now in general use has certain disadvantages, particularly the electrical portion of such machines, wherein variations in resistance coils and various other inconsistencies occur when electric current is utilized in high precision work. This is because in any source of electrical power, regardless of community, fluctuations in voltage occur which cause the difficulties just mentioned. In usage, the resistance of the wires varies and this often sets up a circuit that is too weak to properly actuate the wheels in accordance with the speed at which the machine is operated. The

selective or analyzing means used in the most advanced machines at the present time are generally made up of a plurality of wires of a comparatively small diameter, and it is very easy for these wires to bend or break, in which case one or more wires catch the card itself and tear 30 it or cause it to move from its desired path. This necessitates shutting down the machine to remove or straighten out the card if the card continues on through, as inaccuracy in tabulation may be caused by such continued movement of the card. The points of thesewires often become burnt or carbonized; hence the voltage of the current supposed to flow through them is changed or varies and the proper timing of'operative movements of the machine parts is interfered with. Magnets must be used with this type of machine and the fluctuations of the current, due to overloading, etc., will frequently cause their operation to be irregular. The mechanism of the electrical machines is very involved and expensive and the entire machine unnecessarily heavy and cumbersome. I

The above are some of the reasons why it is highly desirable to eliminate the electrical contact portion and to this end I have produced a tabulating machine that is mechanical throughout, the only use I make of electricity being as a source of power. Of course, any suitable source of power will do, but I prefer the electrical current.

Another object is to simplify the resetting of the accumulators of the recording means. This is now accomplished in other machines by reversing the wheels two or more revolutions from their normal direction of rotation, but in my new device in resetting, the wheels are rotated 5 but once and in their normal direction which adds to the efliciency of operation and eliminates the necessity of the additional mechanism for reversing the wheels. Another and further object of the invention in connection with resetting, 10 is the provision of normal means by which the analyzing elements are mechanically reset after each cycle of operation.

A still further object of the invention is to provide a novel means for resetting the wheels 15 whereby they are reset in a much shorter time than heretofore and which is done automatically after each print. However, this may also be accomplished manually and expeditiously, as may be desirable when a card "slips time in mov- 20 ing through the machine, and thus interferes with the proper operation thereof. In such a case it may be desirable to stop the machine, which upon starting up again and upon the manual manipulation of the resetting device, all of the counters will be reset at zero.

It is my belief that the principles and elements involved in resetting andanalyzing, in accordance with my invention, are broadly new.

General When the back of the machine is referred to, it means the end at which the cards are deposited after 'the information thereon has been indexed or tabulated by passing under the analyzing roll, and "front refers to the end at *which the tabulating is done.

7 1 Number] refers to the left-hand side plate of the machine and 2 to the right-hand side plate, the side plates resting upon and being secured to a suitable base A. The cards are placed in a; hopper 3 from where, by'means of the reciprocating feeding plate hereinafter described they 5 are fed to the cylindrical roll 5 which has circumierentially arranged therein a plurality of rows of oblique sided cam recesses. This roll which is shown in detail in Fig. 9 and to be hereinafter described, cooperates with another roll under it to take the information from the card and to continue the movement of the card to another set of comparatively narrow rollers t and i (Fig. 1) that also have a set of corresponding rollers thereunder whereby the card is moved under the guides i3 and caught by the rollers Q and it carried by the shaft ll. lhese rollers also have correspending rollers under them, all rollers on the right-hand side plate being shown in Fig. 5.- The miides 5 may be placed at whatever intervals are found expedient, depending on the width, texture and other qualities of the records. Numeral i2 designates an upwardly-inclined ledge to assist there is the side plate 2 having cut therein the as recess for the reception of the lifting plate 26, which has therein an opening 27 for the purpose of allowing clearance for a finger of the hand when the cards are placed in or removed from the feeding hopper. At the forward and rearward p sides of the hopper are guides 28, 29, 3 and 3i, respectively, and in addition there may be guides 32 and 33 on the sides. All of these guides may extend to any desirable height above the plates 34 and 35 of the hopper. A detailed description of the operation of the feeding plate and connected- D will be found in connection with the description of Figures 3 and 4. The knives on the feeding plate 24 move theedge of a card under the roll 5 and its complement below, at which point the data is taken from the card. As the card continues its rearward movement its rear edge" is caught by the rollers 6 and I and their complements, and continued in its path under the guides 8 until the rear edge is caught by the rollers 9 and") by which it is forced to slide up the incline l2 and partially under the cards already in the receiving hopper 36, the movement of the card which brings it to its final position in the stack being caused by a means that will be presently described.

The rollers 9 and III are rigid on the shaft H hidden-from view by the ledge on the upper part of the side plate I. .At the forward ends of arms 38 are bearings 39 positioned on the non-rotatable shaft 30. The rollers 6 and I are rotatably mounted on stub shafts and are held down on their supports on the cards by means of the springs 4| and Ma, one end of each of which is fastened to brackets supporting the rollers on the roller supports, which will be later described in detail; the other spring 4| being fastened to any suitable projections as 42 and 43. The operation of the sets of rollers just described is more which the cards may be stacked. In the lower plate 45 of the hopper 38 a cut-out portion 46 may be provided so that the cards may be conveniently lifted therefrom.

The portion of the machine above described cooperates with accumulator mechanism 53 by means of the push rods 54, some of which, as indicated at 5| and 52, may be bent orcurved at the proper angle to conform to the difference in width of the analyzing and tabulating portion of the machine, there being a push rod 54 for each active numeral wheel assembly. Others of the push rods according to. their grouping with relation to the tabulating mechanism, will be differently formed, for instance, those arranged at the center of the machine or substantially so, will be practically straight, while those off to the sides will be bent or formed like those shown in the drawings, Fig. l. The accumulator mechanism is supported by the side supports 55 and 58, as is 1 a cross niember 51 to which may be attached in any suitable manner a safety member 58 which is positioned over the forward ends of the push rods 54 in order to prevent their ends from becoming dislodged from their rocker arms or actuators to which they are removably attached. A sprocket and chain drive 59 operates a series of gears and a shaft, not shown in Fig. 1, but which will be particularly described in connection with Fig. 25.

The printing mechanism, best illustrated in Figs. 20, 21 and 25, is arranged so that it may be swung forwardly from the machine toward the operator in order that the operator may view whatever has been printed on the sheet. This section which contains important elements of the printing mechanism is released by pressing down on either or both of the thumb pieces 60 and SI of the latches 82 and 63 which are pivoted at 84 and 85, thus raising the rear ends 86 and 661: off of the pins 51 and 81a. There is a shaft 68 which may carry any desirable number of rollers, spaced conveniently, the rollers being pressed against the paper roll' 69 to hold the paper or record sheet that passes over the roll in smooth condition. The latches 52 and B3 perform the additional function of releasing the tension of the rollers on the paper through the medium of a lost motion device which is shown and described in Figs. 23 and 24. The shaft 58 is mounted in bearings on the side plates II and I2. The roll 59 may be turned by either or both of the knobs I4 and I5 and the ribbon reverse mechanism I5 may be positioned in any convenient manner. A register, for the purpose of counting the cards as they go through, is indicated at H, and the mechanism that operates it will be referred to later on.

The mainpurposeofFig. listoillustrateln a general way the relative positions of the various parts. Fig. 2 is mostly a general view, in elevation, of the left side of the machine. It more clearly illustrates the guides for the hoppers 3 and including the forward guide plate I8 of the hopper 36, which plate being broken away in Fig. l. The short bolt IS on left side, and similar bolt 80 on right-hand side support the shaft and prevent it from rotating. Nuts 8| and 82 are threaded on the reduced ends of the studs 42 and 43, while the bolts 83 and 84 support arms to be described in connection with Fig. 6. The other terminals in the side plate I are the ends of various shafts and retaining screws for a purpose to be later described. The cap 81 covers an opening at the end of the cylindrical roll that is directly under the bearing that supports the roll 5.

The safety member 58 extends-rearwardly from the cross piece 51 (Figs. 1 and 2) andrests just above the forward ends SI of the push rods 54. The ends 9| consist of forked or bifurcated portions 92 (Figs. 1 and 18) having pins 93 across the gap of the fork, the pins resting in recesses formed in the upper ends of the rocker arms, later to be more particularly described. On the outside of the plate is a bell-crank 94 having a handle 95 which may be manually operated to reset the numeral wheels to zero.

In the upper portion and at the extreme front of the machine is a means for holding the latches 62 and 63 in latched position, which consists of a barrel or sleeve 91 fastened to the side plate II and having a spring located therein to normally urge the plunger 98 upward. The plunger pushes against the under side of the handle and thus locks the latch on the pivot 54, thereby forcing the rear end of the latch down on the retaining pin 61. This arrangement is preferably provided on both sides of the machine. The numeral 99 designates a handle for the purpose of disconnecting the pawl and ratchet of the paper roll to permit of its being rotated in either direction.

A portion of the machine which comprises in part plates II and I2, pivots and swings on the shaft I0 I and in order to retard the movement of this portion and to relieve the operator of the necessity of lifting its entire weight, a retarding means I02 has been provided and is preferably located on the under side of the machine. It consists of a rod I03 that works through any number of suitable supports 104 and I05, and at appropriate points are collars I06 and I0! which are fastened rigidly to the rod I03, the collar I06 'being for the purpose of limiting the forward suitable means such as the screws or rivets H2. 7

When the front portion is swung away, the wheel III will turn, thus pulling the chain H0, which, in turn, will pull the rod 6 03. This movement will continue until the collar I06 contacts the support I 04 at which point it will stop. The same movement compresses the spring I00, which action takes up part of the weight of the front portion, and when it is desired to return said portion to normal position, the tendency of the spring to expand will assist in the latter operation. It will be observed that the collars I08 and I0! may be moved when the screws I I4 and I I 5 have been loosened and in this manner the distance through which the rod I03 travels may be determined and the tension of the spring I09 may be adjusted to any suitable degree;

The cable II5 indicates a source of electrical power which I prefer to use for solely driving the machine, and legs H1 and H8 may be any conventional supporting means.

Feeding hopper and associated parts Figure 3 is a front elevation and illustrates, in detail, the construction of the feeding hopper 3. The side plates I and 2 have any suitable number of screws I26 and i21 therethrough to hold the assembly in proper position. The cross bar 9253 has re'arwardly-extending arms I123 and i291; connected to its respective ends as shown in Figs. and 25 and the lifting plate 26 is attached to the cross bar I28 preferably at the center (Fig. 3) .in order to lift the cards that are in the hopper 3. The top of this plate is bent at approximately right angles to the vertical portion and itsrear end has a cut-away section in which rests a stationary support i3 for the cards to slide over. When what I designate the no-card mechanism shown in Fig. 15 is operated, due to the last card having passed between the rolls 5 and I65, or in other words, when there is not a card passing between the rolls, the cross bar I28 will be moved. upward, thus raising the plate 26, which in turn, lifts the cards that may be in the feeding hopper above the feeding knives IISi and i3Ia. As stated above, at the end of a run, theplate 26 will assume its raised position, so that whenthe next batch of cards is placed in the hopper 3 they will be held out of reach of the knives i3i and itia .until the operator is ready to send them through. The cross bar I28 is manually lowered when the machine is started by the means shown in Fig. 25. The knives I3I and E3Ia are adjustably fastened to the forward edges of the plate '24 by means of the screws i32 and I33 and the slots I34, I35, their height above the plate being determined by the thickness of the card. The numeral I31 designates an oscillating arm having its upper end connected to the cross bar 538 by means of the link M0. The link I60 is pivoted to the cross bar I38 and the upper end of the arm I31, as indicated by 142. 'The oscillating arm I36 which is on the -opposite side of the machine from the similar arm I31, has its upper end connected to the cross bar I38 by a link I39 and pivot. I42 and I43, or similarly to the arm I31 (Fig. 4). These fea-' tures are shown clearly in Figs. 3, 4 and 5. The

cross bar I38 is riveted or otherwise fastened to the under side of' the plate 24 and when the arm I31 is moved toward the rear, the knives I3I and I3IaLwill catch the lowermost card-and. move it rearwardly to a point where the roll 5 and-the roll under it will grip the rear edge of the card and continue it in its movementtoward the rear of the machine. On the rear plate I44 of the,

hopper is an, adjustable guide I45 which may be moved vertically when'the screw I46 has been loosened and it is normally positioned approximately the thickness of the card above the card support I 41 from which extends the card-supporting fingers I30, I48 and- I49i'f Referring to Fig. 4,.it will be seen-that the 05- I cillating arms I36 and I31 are rigidly fastened ,I6I (Figs. 5} 6, 11 and 14), whereby the reciprocator I59 is moved backward and forward, thus rocking the arm I31. The cross bar I38 is fastened to-the under side of the plate 24 and is shown in Figure 4, said plate being in its foremost position. As the: arms I36 and I31. are moved backward or toward the back of themachine, the plate 24 slides in the guides I62 and I62a, a card is engaged by the "knives I3I and I3Ia, is slid over the fingers I30, I48 and H8 i (Figs. 1 and 4) under the adjustable and the rear edge of the card is then caught by the pair of rolls, one of which isnumbered 5. The main body of the card support illl is fastened to the block I63 that extends substantially across the width of the'hopper 3, this block I163 being the element to which are pivoted the numerous analyzing levers to be presently described. The slot itdin the'back plate M l permits the vertical movement of the adjustable guide i 35.

' The side elevation and partial section shown in Fig. 5-illustrates the complete progress of the guide 555 56 to the accumulator wheel mechanism to be described later. The card is then picked up by the next set of narrow rollers 1 and 566. The card slides under the guides 8 and is then caught by the last set of rollers 3, i0 and i671, and as these rollers will not move the card the entire distance into the hopper 36, there is provided a stacker we having at its top a raised portion 869 that engages the 'forward edge of the card and pushes it against the rear plate 64. As explained in con-' neetion with Figure 1, the angular edge [It of the bottom 45 will raise the rear edge of the card so that it will slideunder the over-hanging porton of the cards already in the hopper. The stacker I68 moves in two planes-that is, it rocks back and forth and also up and down, and these movements are accomplished in the following manner. The shaft i6i is driven from. the motor by any suitable source of power, and rigidly fastened to the shaft is a cam IN on the periphery- .of which the roller I12 bears. This roller is positioned in the bifurcated end 913 of the arm H14, mounted on the shaft I15 and is loose thereon. Fast to the shaft is a short arm H16 having one end of the spring I11 attached thereto with its other end attached to the end I13 of arm I14 for the purpose of holding the rdller i12 against the cam I". The stacker I68 is pivoted to the rear end of the arm I19 at I18, and as the cam I1I revolves it raises, and lowers the rear arm I19 thus imparting the same movement to the stacker I68, and this motion is synchronized with the movement of the cards, so that the raised portion I69 will be out 'ofthe path of the card until The back and forward movement of the stacker, is synchronized-with the movement-of the card by means of the eccentric I80 that is mounted on the shaft I8I The eccentric is revolved with' the shaft I8I and by reason of its engagement r with the'stacker arm, brings about the said backward and forward movement. Asthe shaft I8I revolves, the-eccentric I80 is moved backward and-forward, thereby imparting an oscillatory motion to the stacker. The stacker is preferably in the formof a frame having two upstanding similar arms I68 connected by the raised portion I69 which. is of suflicient width to inf sure that the cards are pushed evenly into the hopper and properly stacked. The wheel I81, the

tends forwardly and has an adjustable connection I83 with the link I84 pivoted at I85 to the upper end of a short curved arm I86 on the stacker I66.

Power transmission mechanism The purpose of Figure 6 is to illustrate the manner in which power is applied to theva'rious sets of rollers; how they are arranged to permit passage therebetween of the cards, while pressure is flexibly being applied to them, and the power source of other mechanisms.

By reference to Figures 6 and 6a it will be seen that the shaft 262 has hearings in the said plates I and 2 and. carries the analyzing roll 5, while the shaft 203 is rotatably mounted in the links 261 and 201a on opposite sides of the machine, the links being pivotally mounted on similar studs 206 projecting from'the side plates. Springs 269 and 26911 with their lower ends connected with the links ,and their upper ends connected to pins laterally projecting from the side plates, serve to hold the rollers and I65 in contact with each other, in which position they remain except when the record card is passing between them. Gear wheels 264 and 265 are fast to the shaft 202 and meshing with the gear 265 is an idler gear 206 mounted on a short shaft 2I0 in the side plate 2, which gear in turn meshes with the drive gear 2 onshaft 29I, through which shaft and gear the power for driving the upper set of gears is furnished. The gear 264 meshes with a similar gear206a on the shaft 203, whereby the rolls -5 and I65 are rotated in unison.

The upper pair of rolls 6 and I and the lower pair I66 (Figs. 1, 5 and 6) are operated by means of the gear 2 I2 meshing with the power gear 2 on shaft 29L the gear 2I2 and the roller I66 being on the shaft 2I3. which shaft spans the space between the side plates I and 2 and has bearings in the plates. The upper pair of rolls Sand 1 and gear 2 I4, as well as a similar gear on the lefthand side of the machine are mounted on stud shafts 2I5 which are located in the hangers 2I6 pivoted as at 2|! to the side plates I and 2. The hanger 2I6 is held in lowermost position by the spring 4Ia that has one end fastened tothe upper arm 2I9 of said hanger and the other fastened to the stud 43 in the side plate 2, and the other hanger 2I6, adjacent plate I, is similarly infiuenced by a spring 4| with one end attached to he hanger and the other to the stud 42 on plate I. When a card is caught by the roller, the spring will give sufficiently to permit its passage therebetween. but at the same time will firmly hold it.

The third set of rollers-that is, those closest to the rear or ID and I61, work on the same general principle as the middle set and is provided for the same purpose. The rolls 9 and i6 are rigidly fastened to 'the shaft II (Fig. 1), and there is a complimentary set of rolls I61 positioned immediately below them (Fig. 5). At the extremity of the shaft II that has a bearing in plate 2 is a gear 222 that is adiacent to the side plate 2. The lower gear 223 is mounted on a shaft 224 that has bearings in the side plates I and 2. The gear 223 on. theshaft 224 meshes with the idler gear 255 which rotates on the stud shaft 225 on the side plate 2 and is meshed with the motivating gear 221 on the shaft I8 I which is driven by shaft I6I (Fig. l3 the power being transmitted to the shafts II and 224 by the intermediate gear 225. as will presently be more particularly described. As is the casein the other sets of rollers, provision must be made to allow clearance for the passage of the card and this is accomplished by having the shaft II positioned in the'arm 38 that is pivoted at 236, and said arm has fastened to its other end one end of a spring 23I whose upper end is fastened to the stud 43, the spring serving to exert the pressure on the card as it passes between the rolls to properly feed the card. The arm 38 and the spring 23I are, duplicated on the left-hand side of the machine or adjacent to plate I,

It is to be understood that the distance that the gears are moved away from one another by the passage of a card is approximately the thickness of the card and is so small that it will have no appreciable eifect on the relation of the teeth conventional type and is operated by means of the gear wheel 243 meshing with the large gear Analyzing mechanism Figures '1, 8 and -9 illustrate certain mechanisms which, so far as I am aware, thoroughly distinguish my invention from the prior art to which it belongs. This particular portion of the machine I believe to be radically new in the perforated card-control tabulating machine art. In Figure 7 is shown the upper roll 5 keyed to the shaft 202 by means of the key 245. This roll is preferably made up of a plurality of hardened steel cam disks 246 having cut in their peripheries the cam-sided recesses 241 and the plain circular spacer-disk 248. These spacer-disks space the cam-disks to conform to the space between the vertical columns of the record card 249, and in number, include all column designations contained on the card. These designations, as usual, may be minutes, names, months, or any other designations that the exigencies of the situation require, or a coding thereof. The analyzing levers 250 have heads I thereon which are adapted to protrude through openings like 252 in the card 249, or through the perforations therein, as it is passed between the rolls 5 and I65. It will be observed that there are nine indentations or 'recesses 241 in the disks 246, the one on the right hand side corresponding to the digit I and'progreasing toward the left to the digit 9. The cards 249 passing between the rolls 5 and I65 have already had holes punched through them at certain points to indicate certain information in the particular column in which the hole is punched, which is in accordance with the practice when this type of tabulating machine is used. The lower roll I65 is preferably made with a plurality of sections or disks, some of the disks 253 being of a greater diameter than the others; in other words, they alternate with the spacing disks 254 which are of smaller diameter, thus providing clearance for the head 25I and the necessary freedom of movement of the lever 250. When the head 25! of the lever 256 enters a hole in the card, the information thereon will be transferred through the push rods 54 to the accumulator mechanism Due to the angular form of the head 25I and the similar form of the recesses 241, a head 25I is 4 50 thereby forcing the forced down. by the rotation of the roll 5, thus recording the data. taken from the card. The roll 565 may be made in a-solid piece, but it is preferably made as above described and as- 5 sembled on the shaft 2%.

In Figure 7 the head 258 is shown in its lowermost position-that is, just above the disk 2%. The pivot block or support I63 in which is held the elongated pivot pin 251 upon which the 10 analyzing levers 250 are pivoted, is common to all of the levers. The block has recesses 258 to permit-positioning and movement therein of the levers 25d and also on the block I63 is an anchor 259 attached to the block by any convenient.

means such as screws 266 which are for the purpose of retaining one end of the spring 26L the other end of which, is fastened to the lower arm 262 of the lever 256 at 263, the spring tending to raise the head 25i'upward against the card 259 and in position to instantly enter a hole in a card when one becomes available. In this figure the analyzing lever or bell-crank 258 is shown in its inactive position,- but is just on the point of protruding through the hole 252 and entering, one of the recesses 2.41, which, in Figures 7 and 8, is the digit 5 recess. When the head 25B is held down due to the absence of holes in the portion of the card passing over it, the various elements will be in the position shown in this figurethat is, the'lower arm 262 of the lever 250 is positioned over the rear end of the.

push rod 541. When the head 25i enters one of the recesses 2M (Fig. 8) the lower arm 262 of 40 working in the recess 266, there being, it be understood, a recess in the comb for each push rod, which construction assures the true short vertical movements of. the push rods in their operation. After these. movements have taken place, the parts will have assumed the position shown in Figure 8, and continued rotation of the roll 5 will produces. cam action by reason of the formation of the recess 2d?! on the head 25d and push it down to its original position ZI forwardly t0 actu ate the rod 56 to permit the tabulating or accumulator mechanism to operate. After the rod Ed has moved the required distance and immediately after the digit 1 of the record card has passed from between the two rolls, the arms its and I891; (Fig. 5) arelowered by the mechanism shown in Figures 11 and'ld, thereby moving the comb 265, downward, thus also moving push rod 5d downward so that the arm 262 may 60 be pushed forward to its original position through action of the horizontally positioned plate 26?. The actuating elements for this movement are also described in connection with Figures 11 and 14. These movements just described are timed to take place immediately after the rods 54 have been lowered or reset. The numeral 268 designates a base plate which is'provided adjacent f the rollers 5 and I65 and positioned so as to support the card during its passage through said rolls.

Figure 9 is a view of the upper roll 5, partly in section, there being omitted the greater part of the recess-containing disks and the spacerdisks. The spacer-disks 238, as well as the recessare held com er by means of a retaining collar 26$,which is threaded on the threads 216 (if the shaft 2%. On the other end of the roller there is provided a groove 27!, which is between one of the spacer-disks 2&8 and a collar 272. The no-card lever 69% op- 5 erates freely in the groove 2H between the threaded disk 212 and the adjacent disk 2%, and it will be noted that a disk 2'53 is providm which is of lesser diameter than the associated disks to permit am am of the no-card lever 8% to work therein without touching the disk 2'83.

At this point I desire to; place emphasis on the construction andoperation of the improvements shown in Figures 7, 8, and 9, because of my contribution to this art I have eliminated a vast number of parts usually found in-machines of this character, increased the efiiciency of 'the machine both as to volume of work turned out and its accuracy, and have reduced the over-alldimensions of the machine byat least two-thirds, The troublesome brushes, magnets, resistance coils and electrical connections have been eliminated. As is evidentfrom Figure 1, the indexing roll 5 may be of any desirable width and diameter to adapt it to analyze cards of various di- 25 mensions. Obviously, there must be a.- plurality of analyzing levers 259, a similar number of push rods 5% and numeral wheel assemblies or wheels in this mechanism, although it is not a necessary requisite that all of them be used at one time. The number of columns to be analyzed on a card is limited only by the number ofrecessed disks 2% in the roll 5, and a corresponding nber of the elements that cooperate with said disks.

Figure 10 is a sectional view of Figure 4 looking in thedirectionof the arrows and illustrates the manner in which a plurality of levers 260 may be hung on a common pivot 25F (Figs. 7 and 8) in the pivot block 963. The slots 2% are separated by the partitionsdld and the projection of the inclined face 2'55 is indicated at applf hd= mately the center me block, while the lower side of the pivot ng for the pin 25?]. is in- N dicated. at are, the bearings being open end recesses so that the levers ZSb may be first mountt5v ed on their 'pivot god, and. the rod and levers simultaneously placed in position.

' Resetting mechanism for the' analyzing levers In Figure .11 the mechanism for resetting the analyzinglevers 25b is shown in detail. A, portion of the card-feeding mechanismalready de- Y scribed is'shown, as well as the actuating-means therefor, which has also been'described; Onthe shaft i6i is a cam 28.5 upon whose periphery rides a. roller 286 located in the ,rear end of the arm I88, the forward end of the arm being rigidly fastened on a sleeve 290 which is loosely mounted on the revolving shaft 295. Also, on the sleeve 296 is located the upstanding arm 292a having the two-part push bar 2931: pivoted to it at 294a, and pivoted to the bar at 2950, is the other section 296 of the bar, a pivotal connection between the parts permitting a straight horizontal thrust of the bar in its movements, and also the slight up-and-down movements which are required of the bar. The push bar carries the plate 261 which is arrangedto slide back and forth in the opening 29712 in the arm IBM. The analyzing elements shown in this figure are'in the same relative positions as they are in Figure 81. The cam wheel i8ia having the four elongated notches 298a therein, is located at the right-hand side of the machine, with a similar wheel I81 on the left-hand side. These wheels are fast on the r"-- volving shaft 29I, and running on their peripheries are the rollers 299 that have bearings on studs fastened in the arms I89 and I89a. The rollers 299 are held on the cam wheel I8Ia by means of thespring 300. one end of which-is fastened at 30I to the arm I89a, the other end being fastened at any convenient point such as the bottom of the machine. The spring 302, fastened to the arm l89a at 303 and also to the arm 292a at 304, holds the roller 286 on the cam 295, and normally, holds the plate 261 in its rearmost position, that is, out of reach of the lower arm 262 of the analyzing lever 250. Cam wheel IBM is timed to make one-quarter of a revolution for each card passing between the rolls 5 and IBS-in other words, four cards pass through for each revolution of this cam, and when the roller 299 drops into'one of the notches 298a the arm I89a will rock on the shaft 395 and the parts carried thereby will drop a distance equal to the depth of a notch in the wheel The comb 255 which is a part of the arm I89a, will force the rear ends of the push rods 54 down a suflicient distance to allow the lever arm 26'! to ride up over the rods and thus be in proper position for a new card. or in the position shown in Figure '7. Timing of the cam wheels I81 and I8'Ia is such thatv immediately after the rods 54 have been pushed down the cam head 306 will raise the arm I88, thus moving the arm 292a, the push bar 293a and the plate 281 forwardly, as shown in dotted lines in Figure 14. where the plate contacts the arm 262 and forces it forward- 1y to assume the position over the rods 5|, as shown in Figure 12. Obviously. this movement lowers the head 25I and lowers it to such an extent that it is not only withdrawn from the hole 252 in the card, but is moved completely below the path of the card 249 and will offer no resistance whatever to the entrance of the next suc-. ceeding card, but upon entrance of said card it will be released by plate 251 to allow the head 25I to contact the under side of the card. The movements'of the two chains of elements just described occur once for each card with the exception that the backward movement of the pl te 261 does not take place when there is not a card passing between the analyzing roll 5 and the roll I55. In Figure 12 the analyzing levers 250 are all held in the position shown. by the p ate 291 which plate'is in the position it assumes when the no-card lever I90 is in its normal position, as shown in solid lines in Figure 14.

Figure 13 illustrates the manner in which the,

which the arm I98 on the sleeve 290 is held in its upper position (shown in solid lines) when the cam head 30B is not holding it up, will be described in connection with the next four succeeding figures.

"No-card control mechanism The general operation'of the no-card control is illustrated in Figure 14-, and the details thereof in Figures 15, 16 end 17, and as it is neeessary to overlap the description of these figures,

all of them will be considered at the same time.

There is a groove 2'" in the roll 5 and directly under it in the roll I is a similar groove 309; these grooves being arranged to accommodate the rear arm 3I0 of the no-card lever I93 which is hung on the pivot rod 257 in the pivot block I53. The roll IE5 has a plurality of these circumferential grooves 309 extending across its entire length to accommodate the numerous anaand these grooves are preferably formed by mak ing up the lower roll assembly by alternating disks having different diameters, as illustrated in Figures 6a. '7 and 8. The arm 3I0 is normally urged to its upper position by means of the spring 3i I, and when cards are passing between the rolls they will force the arm 3I0 down into the groove 309 where it will be held as long as cards are passing over it, because, before the trailing edge of one card has passed completely beyond the arm, the leading edge of the oil-coming card will have assumed a position to prevent the arm from being raised. While the arm 3P3 is being held down it is in the position shown in dotted lines in Figure 14, and when a card fails to come through, it assumes the position shown in solid lines, there- 'by moving the lower arm 3I2 rearwardly from the position shown in dotted lines to t-hlt shown in solid lines, and when it takes this position it will be caught by the latch 3I3 which is the end of the forwardly extending arm 3 which is rigidly fastened to the sleeve 290 mounted on the shaft 29I. As long as the arm 3I2 is int-he dotted lyzing levers 250, as well as the no-card lever I90,

line position it will be out of the path of the upand-down movement of the latch which movement is caused by the roller 299 riding on the cam 285. The only point at which the latch 3I3 is in engagement with the arm 3I2 is when the cam head 306 has raised the arm I88 to its up er solid line position. thus lowering the forwardly ex ending arm 3, which constitutes the latch, and these relative positions, as indicated by the solid lines, will be maintained until another card passes over the arm BIO of the no-card lever. The card-feeding mechanism is synchronized with the rolls 5 and I95, and the,cams I81 and 285 in such a manner that the -lea dirm edge or margin of the incoming card will be picked up just before the first cam recess 24! in the analyzing roll, which represents the digit 9, has reached the lowermost point inthe revolution of the analyzing roll, and the recesses for the remain ng digits will coincide with the digits, or-holes for the digits on the record cards. The arm 3 is on the left hand side of the machine and the arm I88 is on the right, and there is a slot 3I5 in the plate 287 to permit rearward movement therein of the arrn 3l2. of the no-card lever I90. r

Figure 15. looking from the right-hand side of the machine, illustrates the manner in which the no-card mechanism is operated, and how it is locked in operative position. The arm 3I0 of the no-card lever I90 is shown in its upper posi= tion-that is, in the groove 2! I which is the po= ticn it assumes when there is no card passing between the rolls 5 and IE5 and the same as that shown in solid linesfin Figure 1-1. a As previously described, the arm 3M is normally constantly moving up and down, but when the arm M2 is inoved to its rear position, the lower end thereof takes a position over the extreme forward latch end 3I3 of the arm 3 when it is in its lower position and arrests ts upward movement, thus holding the roller 235 above the cam head :06. The forward movement of the arm 3I2 has permitted the pivoted and spring-backed block 3I6 reached the rearmost point of its movement, onin its no-card position, shown in Figure 15. The movement of the curved lever 3 l t which is caused by the contact of arm I36 with the lug 3% is very slight, but it is sufficient to swing the lever on the pivot 326 which is positioned on a boss 32!! (Fig. 17) in the side plate i. This movement is sumcient to move the catch 322 d of the halfmoon lug 323 carried byarm H23. 11 the catch 322 has been moved from the lug 323, the arm an and thecross bar 828 will be forced upward by the action of a spring 565 which is posh tioned on the outside of the plate 2, and will be described in connection with Figure 25. The arm are and its complement 123a, which is on the 20 inside of the plate 2, will be described in 'at 32:3, Figure 15, and the upward movement thereof is limited in any convenient manner.

connection with Figure 25. The arm ltd and its complement l29a, which is on the other side of the machine, are pivoted in the sides, as indicated The operation 'of these elements will nowbe described, starting from the point just prior to the beginning of a card run.- At the end of the last run, when the cards cease to pass-between the rolls, the operations above described took place and the elements assumed the positions shown in Figure 15. A new batch of cards is now placed in the feeding hopper-and the motor is started. A lever H described in connection with Figure 25 and rigidly connected with the arm 829a, and, through the cross bar 28, to the lid, is pressed to lower these arms we and 62% andpermit the catch 322 to ride up over the lug 323 and thereby hold the arms in their lowered position. This action lowers the card-lifting plate 26' (Fig. 3) to permit the cards to be fed by the feeding apparatus which is constituted in part by plate 26 and knives ta i, and when the first card passes between the rolls 5 and N5 the arm dill of the no-card lever ltli will be. pushed down thus moving the arm 3B2 forward to the position shown in dotted lines in Figure 14:, and lug 328 r on the arm 3H2 presses against the inclined plate 329 which 'is held to the block tilt by means of, the screw 33d. This'movement rocks the block on the pivot 3877 against the tension of the sp 33%! and moves the lug 3H8 flush against the curved lever 3 l9 and out of the path of movement of the arm 03%. The parts will then rein in the positions just described until the last card passes from between the rollers 5 and H65 releasing the extreme endof the arm 3th, which will then returnto the positionshown in Figure 15, or to no-card position. The pivot 3H and the block 386 are set in the bifurcated end 332 of the curved lever 3i 3. There is'a very short recess 3|5 (Figs. 14 and 15) in the horizontal plate 2% which is solely for the purpose of permittingmovement therein of the arm 3l2 of the no-card.

lever, without interference by the plate.

The numeral 3l3a de'signatesa stop rigidly attached to the forward end of the. arm 354 by means of the set-screw 33 i, and on the sideof the stop adjacent the side plate l is a pivot screw 335 (dotted lines Fig. 15), which serves as a bearing forthe connecting link 335, the upper end of the link beingconnected at 331 to the arm 338 which is fast on the shaft 339 of the register. or counter ll (Fig. 1). The up-and-down movement of the arm 85$ will actuate the link 833.-

aoaavca which in turn, will operate the register through stub shaft ass, for the purpose of counting the cards. As the no-card lever let) latchm the arm 3541 out of operative position the register link will also be at a stand-still and will remain so 5 until the next or succe :n card run. Part of the mechanism now to be described in connection with Figures 18 and 19 has been described in connection with Figures 7 and 8; so will be repeated at this point only sufiiciently to pick up 10 the continuity. The arms i833 and M3912 carry, suspended between them, a slidable plate 261? which is utilized for setting the ang levers 25d. The lower end 3&6 of the arm 2% of the analyzing lever normally rests against or very push rod in a forward direction. The rear end ill'l 2c is preferably held up by spring 264 which is at- 2'. in any convenient manner to the rod and tothe comb 255, the comb having numerous re-. cessm 266 in its lower edge into which the ends of the rods extend for the purpose of guiding them during their forward and backward movements. When motion is imparted to the push rod its forwardends lt (Fig. 18) having therein thepin 93 removably set in. the recess ace of the upper end E of the rocker arm 352, will rock this arm on the so shaft 353,. thus moving the lower end 356 'down ward and rearward, and when this action takes place, the lower end 356 of the rocker arm 352 will force the rear arm 355 of the chor 35d downward, thus rocking the anchor on the t 35 35?, thus removing the head 358 which is carried by the upper arm see of the anchor 35d. from one of the teeth 36d of the dish The toothed disks 368, the numeral disk 362 and the carry and reset disk shown in Figure 19, may 40 be fastened together in any convenient m oer, such for instance as by screws, and they are not rigidly fastened to the shaft 366, but are frictionally mounted thereon to rotate therewith u when operated during tabulation. I

en an impulse is given a rod 541, the anchor 356 will be rocked through the rocker arm 352,

out of engagement with a tooth on thetooth disk dad, thereby permitting the shaft to pick up the whole numeral wheel assembly and carry it with it until the anchor is released to permit it to return to position to engage another tooth to again hold the numeral wheel assembly against rotation. The anchor is held out of engagement with the numeral wheel by the rocker arm 352 until it is released by the downward movement of-the comb 265, which permits rod 56 to be pulled'rearwardly to position under the end 365 of the analyzing lever, by the spring 355, whereupon the spring 363 returns the anchor to toothto engaging position. I

Accumulator wheel mechanism In the analyzing mechanism the head 25l has dropped'into the recess for the digit 5 (Figs. 8 c5 and 18) and when it is forced therefrom by the cam action of the recess, it will ride on the card until the digit 1 recess has passed. In the mean-.

time by means of the rod 54 and the arm 352 the anchor 356 will be held away from the toothed disk 365 until five of the teeth 363 have passed, when the anchor 355 will be released and catch the next succeeding tooth. When the numeral disk assembly has counted up to its limit, or

"nine the int: 316 on the and reset disk 363 as will trip the transfer anchor 311 by forcing the upper arm 318 which carries the head 319, backward only a suflicient distance to permit the narrow portion 383 of the horizontal arm 384 to drop in behind the lower arm 385 of the anchor 311. The arm-384 is pivoted at 386 to the vertical arm 381, which in turn, is pivoted on the shaft 388, and the arm 384 is urged upward by the spring 389, one end of which is fastened to each of the arms. After the narrow portion 383 has dropped in behind the arm 385 and is occupying the notch 398, both of the arms 384 and 381 will be pushed forward by action of the cam 39! of the cam wheel 392 acting on the cam 393 on arm 381, which actionforces the upper end of the transfer anchor 311 backward to engage the stud 394 which is on the next anchor 356 to the right, and allows a wheel to revolve until the head 358 catches the next on-coming tooth 368, which, when-the first and second wheels from the left are considered and the first has added up to its capacity, or nine, one will be transferred to the second wheel, to make a total of ten;

The cam" wheel 392 is preferably made up of a series of disks each having one' cam 39l thereon, there being a cam 39! for each set of arms 381 and each anchor 311. When these disks are assembled on their shaft they extend entirely across the machine,'and indeed, the whole assembly then resembles more closely a shaft having a series of cams onits periphery and the disks are merely described as wheels because they constitute what might be regarded as a series of wheels side by side in compact formation. The

cams 391 are progressively offset so that their action will take place only during the period of accumulative transferring. These disks are rigid on the shaft-394a which seats in the open end bearing 395 of the standard396 which is secured to the block-391 by means of suitable screws 398. Extremities of the shaft 394a turn in the side plates 55 and 56. The arms 381 and 384 are held back against the cam wheel 392 by the'spring 399, one end of which is fastened to the cross member 488 and the other end to the arm 381 at 481 Until the arm 385 of the transfer anchor 311 has been pushed forward, the narrowportion 383 of the arm 384 will ride under the lower end of the arm 385 without any definite action taking place, but when the portion 383 has dropped into the notch 398 it has assumed the position. shown in dotted lines (Fig. 19) and will move the anchor 311 to its new position, or the position shown in dotted lines, but continued forward motion of the arm 384 brings the inclined portion 482 against the roller 483,.

which action lowers the portion 383 so that it starts to ride on the lower end of the arm 385, consequently discontinuing the forward movement of that arm and permitting both of the anchors to resume their normal positions through action of the springs 368 and '38l. This is timed with the action of the cam wheel 392 so that the anchor 356 will permit only one tooth 368 to pass under it before it returns to its normal position, and at the same time the portion 383 will be placed in proper position for the start of a new cycle, or inthe position shown in full lines in Figures 18 and 19. The 'shaft 388 is located in the cross member 484 which also acts as a brace standard 481, which standard is secured to the cross member 488 by'means of screws 489. One

reset operations.

Resetting mechanism The next action to take place, best shown in Figures 20 and 21, is the printing of the totals that have been registered bythe numeral wheels, but it is deemed preferable not to explain the working of the mechanism involved in that function at this point, but to describe the mechanism for resetting of the counters after a print of the totals has been taken and by which the various elements are placed in proper position for a new run of cards.

The resetting operation may be accomplished in one revolution of the numeral wheel assemblies, and by revolving them in their normal or tabulating direction which is always forward or toward the operator as contrasted to the reverse direction, which is the usual procedure. This eliminates the necessity of the elements required for a reversing mechanism, and in addition, the resetting is accomplished in a much shorter time and with greater expedition than heretofore.

There is a thumb piece 96 on a lever 4l6 preferably located on the left side of the machine which, when pressed, allows the elements shown in these two figures to be set in motion for the purpose of actuating the elements that actually perform the resetting operation. In Figure 20 the parts are shown in their normal positions, that is, the positions they take when the tabulation is being done and prior to the printing and The lever 4 I6 is held normally raised by spring H1 and rocks onthe pin 4| 8, and the downward movement of its arm 9 which takes place in the opening 4 l4, in the base A is limited by a stop pin 428 engaging the upper surface of the base adjacent the opening. The rear arm 419 has at its end a catch 42| for engagement with the projection 422 of the dog 423 mounted on pivot pin 424 carried by arm 425, which as shown best in Figure 28a, is a part of the eccentric 434 keyed to the normally nonrotating shaft I8 I, and consequently both the disk and arm revolve with said shaft at such times as the shaft is revolved. Adjacent this disk and mounted on the shaft 18! is the clutch disk 429 which is fastto a sprocket 438, the disk being provided with notches 428 for the reception of the tooth 421 of the dog 423 at the proper time to efiect a joint movement of the .disk and dog carrying-arm 425. As shown in Figure 20, the tooth 421 is held out of the notch 428 of the clutch disk by the catch 42l of the lever B, in which position, obviously, the clutch disk is independent of the dog-carrying arm.

the normally non-rotating shaft l8l. Fast upon this shaft is the eccentric 434 which eccentric, as we have seen, has integral therewith the arm 425, which arm in turn carries the pivoted-dog 423 whose lower end has the tooth 421 adapted to enter one or the other of the notches 428 of the clutch disk 429, when released by a thumb piece 96 for actuating the mechanism for taking a print-all as will presently more fully appear.
